My son has been playing KSP on our computer for a while. Starting in recent days KSP will not load. The progress bar at the bottom of the splash screen chugs along, gets to about 50%, and then resets to about 1/3rd and shows "Module Manager" and will not progress any further. Apologies for not knowing what to do but this is all new to me and I'm just trying to reduce frustration in our house. Any guidance on what to do, short of uninstalling and reinstalling, would be greatly appreciated.
